DETAILED DESCRIPTION

In order to make the objects, the technical solutions and the advantagesof the present disclosure more apparent, the present disclosure will bedescribed hereinafter in a clear and complete manner in conjunction withthe drawings and embodiments. Obviously, the following embodimentsmerely relate to a part of, rather than all of, the embodiments of thepresent disclosure, and based on these embodiments, a person skilled inthe art may, without any creative effort, obtain the other embodiments,which also fall within the scope of the present disclosure.

In the related art, a painting display panel includes a display moduleand a frame surrounding the display module, and a decorative fabric isdirectly adhered onto a surface of a front frame body of the framethrough glue. However, the front frame body is made of plastics, andduring the transportation, the fabric is easily, at an edge of the frontframe body, separated from the front frame body in the case that anexternal force is applied thereto, i.e., the fabric is easily turned upat the edge, resulting in a defective product. FIG. 1 shows aconventional frame where a decorative layer 3 is adhered onto a surfaceof the front frame body, and FIG. 2 is a sectional view of theconventional frame along line A-A′ in FIG. 1. As shown in FIGS. 1 and 2,in the design, the decorative layer 3 is adhered, through glue 2, onto ashowing surface 1 of the front frame body 1 of the frame, and the frontframe body 1 is made of plastics. In this method, the decorative layer 3is easily separated from the front frame body 1 at the edge of the frontframe body 1, especially at an inner edge and an outer edge of the frontframe body 1. During the transportation, the decorative layer 3 iseasily turned up at the edge when an external force is applied to theedge of the front frame body, resulting in the defective product.

An object of the present disclosure is to provide a display device, soas to prevent the decorative layer from being turned up at the edgewhile providing the decorative layer for the display device to meet thedecoration requirements.

As shown in FIG. 7, which is a sectional view of the display device inthe embodiments of the present disclosure, a frame of the display deviceconsisting of first frame bodies, second frame bodies and third framebodies may be used to decorate and secure a to-be-decorated object ofthe display device. For example, the to-be-decorated object may be adisplay module for displaying a painting.

As shown in FIGS. 3 to 7, the present disclosure provides in someembodiments a display device, which includes a plurality of first framebodies 100 configured to form a first frame for defining anaccommodation space. The accommodation space may receive ato-be-decorated object 10, e.g., a display module, i.e., the first framemay surround the to-be-decorated object 10 so as to decorate and securethe to-be-decorated object 10. The plurality of first frame bodies 100is provided with a showing surface 101 facing a user, i.e., a surface ofthe plurality of first frame bodies 100 at a same side as a displaysurface of the display device. A decorative layer 200 may cover theshowing surface 101, a groove may be formed in the showing surface 101at at least one edge, and an edge of the decorative layer 200 may bearranged in the groove, as shown in FIG. 5. To be specific, in FIG. 6,there are four first frame bodies 100 connected in an end-to-end mannerto form the first frame (each dotted line in FIG. 6 represents aconnection position where adjacent first frame bodies are connected toeach other; of course, the adjacent first frame bodies may also beconnected to each other at any other positions). In addition, the fourfirst frame bodies may be formed integrally to acquire the first frame.

According to the embodiments of the present disclosure, the groove maybe provided in at the edge of the showing surface 101 of the pluralityof first frame bodies 100, so the edge of the decorative layer 200covering the showing surface 101 of the first frame bodies 100 may befixedly arranged in the groove. In this way, the edge of the decorativelayer 200 may not easily separate from the groove even when an externalforce is applied to the display device, so it is able to prevent theedge of the decorative layer 200 from being turned up.

In a possible embodiment of the present disclosure, the decorative layer200 may cover the showing surface 101 of the plurality of first framebodies 100 through an adhesive. Of course, it should be appreciatedthat, the decorative layer 200 may also cover the showing surface 101 ofthe plurality of first frame bodies 100 in any other manner.

In addition, in a possible embodiment of the present disclosure, thedecorative layer 200 may be secured onto the showing surface 101 of theplurality of first frame bodies 100 through an adhesive layer, e.g., ahot-melt adhesive layer 102.

When the decorative layer 200 is secured onto the showing surface 101 ofthe plurality of first frame bodies 100 through glue, there is thefollowing problem. At first, it is necessary to apply the glue onto theshowing surface 101 of the plurality of first frame bodies 100, and thenplace the decorative layer 200 onto the showing surface 101 of the firstframe body 100. In this regard, during the entire adhesion process, thedecorative layer 200 may easily be wrinkled, and once there is anywrinkle, it is very difficult to repair.

In some embodiments of the present disclosure, the adhesive layer, e.g.,the hot-melt adhesive layer, may be arranged between the decorativelayer and the showing surface, so as to adhere the decorative layer ontothe showing surface. As shown in FIGS. 3 to 7, the adhesion of thedecorative layer 200 may be performed as follows. At first, a hot-meltadhesive film and the decorative layer 200 may each be sliced intoportions with a small size (the decorative layer 200 is easily deformeddue to a stretching force, so a tensile force needs to be controlledduring the slicing, so as to prevent the occurrence of threads at theedge of the decorative layer 200). Next, each portion of the hot-meltadhesive film may be adhered onto the corresponding portion of thedecorative layer 200 through a thermal laminator (due to the tensiledeformation of the decorative layer 200, no tensile force may be appliedto the decorative layer 200 during the feeding and delivery ofmaterials, so as to prevent the decorative layer 200 from being deformeddue to the tensile force). Next, the portion of the hot-melt adhesivefilm together with the portion of the decorative layer 200 laminatedthereto may be cut into a desired shape through a die-cutting machine(during the cutting, a sharp tool needs to be provided, so as to preventthe edge of the decorative layer 200 from being turned up due to toolong broken threads). Next, a waste material, e.g., the superfluoushot-melt adhesive film and decorative layer), may be discharged. Then,the acquired portions of the decorative layer 200 and the hot-meltadhesive layer may be placed onto the showing surface 101 of theplurality of first frame bodies 100, and heated to melt a hot-meltadhesive, so as to adhere the decorative layer 200 onto the showingsurface 101 of the plurality of first frame bodies 100.

Hence, when the decorative layer 200 is adhered onto the showing surface101 of the plurality of first frame bodies through the hot-melt adhesivelayer, the hot-melt adhesive layer may be laminated onto the decorativelayer 200, then then placed onto the showing surface 101 of theplurality of first frame bodies 100, and then heated to melt thehot-melt adhesive so as to adhere the decorative layer 200 onto theshowing surface 101. In this way, the decorative layer 200 may maintainflat and smooth during the entire adhesion process, and no wrinkle mayoccur. As a result, it is able to improve the yield of the product aswell as lamination flatness of the decorative layer 200.

In addition, in a possible embodiment of the present disclosure, asshown in FIGS. 3 to 7, the showing surface 101 may include an inner edgeadjacent to a central region of the first frame and an outer edge awayfrom the central region of the first frame.
